I don't know how you managed to figure out the problem so quickly but I just tried this with the FFmpeg command:
Code:
ffmpeg -i input.wav -af "aeval='-val(0)':c=same" output.wav
...and it seems to have worked! Thank you so much for both the response and the solution.
Do you have any idea what this would have been caused by in the source video, or maybe more importantly, why it only seemed to affect a (generally older) portion of mobile devices?
